Abstract :
In order to identification, classification and soil formation in Islamic Azad University of Fasa branche’s lands were studied. These lands including two parts, one of them with 12 hectares extent located in 5 km of the west of Fasa and other one with 220 hectares extent located in 15 km of the west of Fasa in Fars province. Soil moisture and thermal regime is xeric and thermic respectively. For investigations of these lands, topographic maps were used and many profiles were dogged and after soil morphology surveys, soil sampling and physical and chemical experiments were done. Investigation of physico-chemical and morphological properties of these soil showed they were Lomy-skeletal, mixed, thermic, Typic Calcixereots soils. These soil don’t have properties of other orders and have a calcic horizon in xeric moisture regime, therefore these soils are inceptisol.In these soils strongly effect of parent material in soil formation is observed. Light texture and a lot of gravels and cobbles in these soils are caused to increase permeability rate and carbonates leaching from upper horizons and accumulation in soil lower horizons. In calic horizon, lime is observed as pendant concretion and powdery pockets.
